Breast augmentation is the most common operation in cosmetic surgery. The original scope of the operation to enlarge small breasts has been expanded to include the correction of different shapes, nipple size and position, and hanging breasts. In most cases the scar is small and can be placed where it is minimally visible. Frequently an office worker can have surgery on Thursday or Friday and return to work on Monday or Tuesday. This field also includes breast lift and breast reduction operations. These operations are more complex and require longer recovery time.
